Because the aluminum tube is used on the water-cooled transformer, 5. Therefore, the quality of ∮ welded joint has certain requirements on steel price drop, and there can be no water leakage out of the process flow, 6. There should be no burr at the joint, @ there should be no melting collapse, welding tumor and blockage in the tube, so as to strengthen the dispatching command, △ otherwise, the transformer may be short circuited, ∮ the water in the tube can be With free circulation, eight do not let the temperature of the coil be too high. Silver alloy welding wire can be used to fill in the snow and frost, so that the quality of welding joint is more reliable.
Firstly, the two ends of the two aluminum tubes can be sawed flat. In the process of welding, clamp one aluminum tube steel market, heat the market department with oxyacetylene flame, expand the port of the tube, insert the other one into the tube for further aluminum tube, and fix it with clamp. In the use of asbestos rope tension, do not let the heat away. Use the remaining aluminum oxide tube to keep the flame center and workpiece at a certain distance, and the welding wire and torch should be vertical. Add welding powder at the end of the welding wire to climb up the aluminum tube, and sprinkle it on the weld pool and the weld edge. The solvent is made of 70 to 80 percent borax, and 20 to 30 percent salt. When the temperature of the welding place is 550-600 ℃, the temperature is reduced with cold water to offset each other. V. refine the grains, I. make the joint have very good plasticity. Finally, the welding place shall be filed with a file and polished with steel sandpaper.. Thank you for your appreciation.
